Abstract (en)
[origin: WO2017084969A1] The invention relates to novel catalysts for oxidative esterification, by means of which, for example, (meth)acrolein can be converted to methyl (meth)acrylate. The catalysts according to the invention are characterised in particular by a high mechanical and chemical stability, even over very long periods of time. This relates in particular to an improvement in the service life, activity and selectivity of the catalyst compared with catalysts from the prior art, which relatively quickly lose activity and/or selectivity in continuous operation, even in media with low water content.
